To all whom itmai 00mm.- I I Be it known that 1, JOHN BYRNE, a c1t1-1Zen of the United States, andresident of San Quentin, California, haveinvented certain new and useful Improvements in Safety-Locks for Bottlesor the like, of which the following is a specification.

This invention relates to improvements in a safetylock for'bottlesor-the like, and has for its object an attachmentwhich can be readilyand easily applied over the head and neck of a bottle or container witha locking means coming in contact with the under surface of the head ofthe bottle other medicine.

The device is simple, consisting of an outer shell with a means locatedtherein which'can be operated by a key when it is desired to remove itfrom the head and neck of the container.

Figure 1, is a vertical central sectional view of, my complete inventionshowing it in its locked position on the bottle.

Fig. 2, is a central sectional View of the same taken on the line 22 ofFig. 1.

Fig. 3, is a top plan view with the cap removed.

Fig. 4, is a detail perspective view of the unlocking member made useof.

Fig. 5, is a detail perspective view of the rotatable member by whichthe unlocking member is raised and lowered.

Referring to the drawings in detail, 6 indicates a cylinder, its topbeing provided with a cap 7, which cap is centrally provided with anelongated slot 8, through which a key 9 may be inserted.

In the cylinder and at the top is located a rotatable sleeve 10, itssurface is provided with two curvilinear slots 11, which act as a cam,the upper portion of the sleeve is provided with a rigid cross pin 19against which the notch end 13 of the key contacts.

The bottom surface of the sleeve 10 is designed to; rest upon a pair ofcross pins 14., which are firmly secured to the walls of the cylinder.6, the same being suitablyspaced apart as shown in Fig. 2, so as to actas a guide for the vertical arms 15 of the unlocking member 16, theybottom of the arms terminating in a ring 17. ring-is situated near. thebottom ofthe cylinder G, as shown and the same is raised and lowered bymeans of the pin 18 connected to the upper ends of the arms 15 andsupported in and riding in the curvilinear slots of the sleeve 10.

On the inner surface of the cylinder (5 and near the bottom is attacheda plurality of inwardly bent springs 19, the bottom ends of said springsbeing securely riveted in position while the inner ends are free, andthe normal tendency of thesame is to bend inwardly and come in contactwith the under shoulder 20 of the bottle head as is clearly illustratedin Fig. 1.

By means of the resiliency of these springs the device may be placed inposition by forcing it downwardly over the head and as soon as thesprings pass over the head and in a line with the shoulder they willautomatically move inwardly, in this manner it will be utterlyimpossible to again remove the device from the bottle except wheninserting the key 9 and turn ing it onequarter around which will causethe pin 18 to ride along the cam grooves and raise the unlocking memberupwardly pressing the. plurality of springs 19 outwardly against theinner surface of the cylinder 6.

This

The free contacting ends of these springs being then removed away fromunder the contact with poisonous substance or dan gcrous ingredientswithout first acting as a warning that such substance and ingredients iscontained in the bottle.

l -iaving fully described my invention what I claim is:

1. A device of the class described com-;

prising an outer shell, a rigid cap mounted thereon, a verticaloperating unlocking member located therein, a plurality of springsattached to the inner surface of the shell and operated by the movementof the unlocking member and a partially rotatable sleeve incommunication with the unlocking member, the partial rotation of thesleeve clevating'the unlocking member and straightening out the springssubstantially as specified.

2. A device of the class described comprising a cylindrical member, acap securely attached thereto, a partially rotatable sleeve supported inthe top of the cylindrical member and provided with cam slots, anunlocking member attached thereto but permitted to operate 'ertically bythe partial rotation of the rotatable member, the motion being impartedto the rotating member by means of a key inserted through the top,substantially as specified.

3. A device of the class described com- JOHN BYRNE.
